1 Claim.

The present invention relates to improvements in bung wrenches for usein connection with the removal of bungs from barrels and the like.

An object of the present invention is to provide a bung wrench which isprovided with a plurality of tool engaging elements whereby bung plugsof various forms may be removed or inserted into barrels and the like.

A further object of the present invention is to provide a hung wrenchwherein a plurality of flat plates of differing widths are provided forengagement with the slots of bungs of varying diameters.

Still another object of the present invention is to provide a bungwrench wherein the tool engaging member is adapted to engage thenoncircular nut for rotating the same and wherein the non-circularhollow open ended member is provided with a core element having aslotted end for engagement with the center portions of one form of bungplug.

Various other objects and advantages will become apparent from thedetailed description to follow. The best form in which I havecontemplated applying my invention is illustrated in the accompanyingdrawings, wherein:

Figure 1 is a bottom view of the present invention;

Figure 2 is a vertical longitudinal sectional view taken substantiallyalong the plane of line 2-2 of Figure 1;

Figure 3 shows an elevation of the left hand portion of the bung wrenchshown in Figure 1, after the wrench therein has been inverted;

Figure 4 is a vertical transverse sectional view taken substantiallyalong the plane of line 4-4 of Figure 2; and

Figure 5 is a detail view similar to Figure 3 but showing the oppositeside thereof.

Referring more particularly to the drawings, wherein like numeralsdesignate like parts throughout, the numeral [0 designates generally thebung wrench of the present invention. The numeral l2 designatesgenerally a handle means and the numeral [4 designates generally a toolmeans associated with the handle means l2.

The handle means I 2 is formed from a flat elongated plate 26 having anangulated end l6 forming a work engaging portion and is provided at itsother end with a reduced elongated portion IS. A hollow tubular element20 encompasses the elongated reduced portion I8, is welded thereto, andprovides a handle portion.

The tool means I4 includes a hollow open ended non-circular socketmember 22 which is welded to a bottom face 24 of the flat strap 26 ofthe handle means l2. The hollow open ended member 22 is shown here ashexagonal but may be of any desired form conventionally used for bungplugs and the like. Axially disposed within the hollow open ended member22 is a shank or core element 28 which has an end portion fixed in anysuitable manner in an opening 30 in the flat bar 26. The core element 28is of circular form and is provided with a transverse recess or kerf 32at its lower end for engagement with a projection within a recess on abung plug. It should be noted that the core element 28 extends beyond abottom edge 34 of the hollow open ended member 22 whereby a tool end 36of the core element may be employed separately if desired.

A pair of laterally extending fiat plates 38 and 40 are secured to theopposite sides of the hollow open ended member 22 and provide a pair oftool engaging members which may be employed for removing bungs ofdifferent forms. As best seen in Figures 3 through 5, the flat plates 40and 38 are of different cross section, the flat plate 40 being ofelongated rectangular cross section while the plate 38 is ofsubstantially square form.

From the foregoing, it will be seen that a bung wrench has been providedwhich is readily adapted for use with bung plugs of varying form, andwherein the bung plugs are provided with either slots, non-circularperipheries, notches or projections.

It will also be seen that a bung wrench has been provided which iseconomical of manufacture and relatively simple.

Having described the invention, what is claimed as new is:

A wrench for polygonal, substantially cupshaped bungs having adiametrically extending rib, comprising a fiat metallic bar having anopening in one end portion, a shank fixed in the opening, and apolygonal socket member for the reception of a hung, fixed on the bar inspaced, concentric relation to the shank, the free end portion of saidshank projecting beyond the socket member and having a kerf therein forthe reception of the rib when said socket member is engaged with thebung.
